Download OpenCms

OpenCms comes in two distributions: The
binary distribution and the
source distribution . The binary distribution contains everything you need to run
an OpenCms website. The source distribution contains the complete source code, as well as the
libraries required to compile the source.

If you intend to run OpenCms, we recommend that you use the latest release. Just download the
binary distribution ZIP file and follow the instructions on the
installation page. In case you
want to work on the OpenCms source code, have a look at the
core build page.

If you want to obtain the latest OpenCms development version, you can get it from our
GitHub repository.
